How about this:
Paul Dirac explained the properties of subatomic particles with this equation:
(iฮณแตโแตฆ - m)ฯ = 0
the variable i stands for the imaginary unit,
ฮณแต stands for Dirac matrices (or gamma matrices). They are 4x4 matrices that encode the spin of the particle.
โแตฆ is the partial derivative with respect to space and time.
m stands for the mass of the particle, while ฯ describes the state of the particle.
Putting it all together, this was able to predict antimatter, and solved a problem in quantum physics, explaining its spin, or angular momentum of 1/2.
